2012-04-04Add support to run SMM handler in TSEG instead of ASEGStefan Reinauer
Traditionally coreboot's SMM handler runs in ASEG (0xa0000), "behind" the graphics memory. This approach has two issues: - It limits the possible size of the SMM handler (and the number of CPUs supported in a system) - It's not considered a supported path anymore in newer CPUs.

From wikipedia: Intel Turbo Boost is a technology implemented by Intel in certain versions of their Nehalem- and Sandy Bridge-based CPUs, including Core i5 and Core i7 that enables the processor to run above its base operating frequency via dynamic control of the CPU's "clock rate". It is activated when the operating system requests the highest performance state of the processor.

2012-03-31Fix issues with x86 memcpyMathias Krause
The x86 memcpy() implementation did not mention its implicit output registers ESI, EDI and ECX which might make this code miscompile when the compiler uses the value of EDI for the return value *after* the 'rep movsb' has completed. That would break the API of memcpy as this would return 'dst+len' instead of 'dst'. Fix this possible bug by removing the wrong comment and listing all output registers as such (using dummy stack variables that get optimized away). Also the leading 'cld' is superflous as the ABI mandates the direction flag to be cleared all the time when we're in C (see <http://gcc.gnu.org/gcc-4.3/changes.html>) and we have no ASM call sites that might require it to be cleared explicitly (SMM might come to mind, but it clears the DF itself before passing control to the C part of the SMI handler). Last but not least fix the prototype to match the one from <string.h>.

2012-03-31Add support for RAM-less multi-processor initKyösti Mälkki
For a hyper-threading processor, enabling cache requires that both the BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram implementation, partial multi-processor initialisation precedes raminit and AP CPUs' 16bit entry must be run from ROM. The AP CPU can only start execute real-mode code at a 4kB aligned address below 1MB. The protected mode entry code for AP is identical with the BSP code, which is already located at the top of bootblock. This patch takes the simplest approach and aligns the bootblock 16 bit entry at highest possible 4kB boundary below 1MB. The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR used by the CAR code in romstage. Adress is not expected to ever change, but if it does, link will fail.

2012-03-30MTRR: add alternate allocation method for odd memory mapsDuncan Laurie
With >= 4GB memory installed we get a memory map split in the middle due to remap that has boundaries that are inconveniently aligned for MTRRs due to the various UMA regions. 0000MB-2780MB 2780MB RAM (writeback) 2780MB-2782MB 2MB TSEG (uncached/SMRR) 2782MB-2784MB 2MB GFX GTT (uncached) 2784MB-2816MB 32MB GFX UMA (uncached) 2816MB-4096MB 1280MB EMPTY (N/A) 4096MB-5368MB 1272MB RAM (writeback) 5368MB-5376MB 8MB ME UMA (uncached) The default MTRR allocation method of trying to cover everything with one MTRR and then carve out a single uncached region does not work for the GPU aperture which needs write-combining type, and it also has issues trying to cover the uneven boundaries in the avaiable variable MTRRs. My goal was to make a minimal set of changes and avoid modifying behavior on existing systems with an algorithm that is not always optimal for a typical memory layout. So the flag 'above4gb=2' will change these allocation behaviors: 1) Detect the number of available variable MTRRs rather than limiting to hardcoded value. We need every last MTRR. 2) Don't try to cover all RAM with one MTRR, instead let each RAM region get covered independently. 3) Don't assume uma_memory_base is part of the last region and increase the size of that region. In this case the UMA region is carved out from the lower memory region and it is already declared as part of the ram region. 4) If a memory region can't be covered with MTRRs >= 16MB then instead make a larger region and trim it with uncached MTRRs.

2012-03-30Prepare the BIOS data areas before device init.Duncan Laurie
Since we do not run option roms in normal mode nothing was initializing the BDA/EBDA and yet Linux depends very much on it having sane values here. For the most part the kernel tries to work around this not being initialized, but every once in awhile (1/300 boots or so) it would end up reading something that looked sane from BDA but was not and then it would panic. In this change the EBDA is unconditionally setup before devices are initialized. I'm not set on the location in dev_initialize() but there does not seem to be another place to hook it in so that it runs just once for ALL platforms regardless of whether they use option roms or not. (possibly hardwaremain?) The EBDA setup code has been moved into its own location in arch/x86/lib/ebda.c so it can be compiled in even if the option rom code is not. The low memory size is still set to 1MB which is enough to make linux happy without having to hook into each mainboard to get a more appropriate value. The setup_ebda() function takes inputs so it could be changed for a mainboard if needed. OLD/BROKEN would read garbage. Examples from different boots: ebda_addr=0x75e80 lowmem=0x1553400 ebda_addr=0x5e080 lowmem=0x3e51400 ebda_addr=0x7aa80 lowmem=0x2f8a800 NEW/FIXED now reads consistent values: ebda_addr=0xf6000 lowmem=0x100000 Change-Id: I6cb79f0e3e43cc65f7e5fe98b6cad1a557ccd949 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: http://review.coreboot.org/769 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-30Make cpuid functions usable when compiled with PICDuncan Laurie
This avoids using EBX and instead uses EDI where possible, and ESI when necessary to get the EBX value out. This allows me to enable -fpic for SMM TSEG code. Also add a new CPUID extended function to query with ECX set.

2012-03-30Make PCI CONF2 support a compile time optionStefan Reinauer
It's not used on any board supported by coreboot but has been detected at run time since ages. No new boards (since 2000?) are using the CONF2 method, so it is unlikely we ever have to turn this on for a board.

2012-03-30Fix coreboot makefiles not to produce half baked output.Vadim Bendebury
It looks like the cbfstool utility generates the output file even when it fails to generate it properly. This causes make, if started second time in a row, after cbfstool failure, to continue beyond the point of failure (as the corrupted output file is present in the output tree, the second make invocation presumes that it is valid, as it is newer than the dependencies). The output file should be created only when successful, in an atomic operation. There could be other places in the make system which require a similar fix, this needs to be investigated further.

2012-03-30Add TPM support to corebootStefan Reinauer
and initialize the TPM on S3 resume This patch integrates the TPM driver and runs TPM resume upon an ACPI S3 resume without including any other parts of vboot. We could link against vboot_fw.a but it is compiled with u-boot's CFLAGS (that are incompatible with coreboot's) and it does a lot more than we want it to do.
